<p>
    角色是一个方法内容元素，它定义相关技能、能力和职责的集合。任务使用角色来指定执行任务的人员并定义这些人员所负责的工作产品集合。
</p>
<p class="node" align="left">
    角色通常由单个人或者作为一个团队协同工作的一组人来实现。一个项目团队成员通常履行许多不同的角色。
    请注意：<b>角色不是个人，也不必等同于工作头衔；</b>角色而是描述个人在项目中应如何作为以及个人的职责。组织的各个成员将有不同的职位或执行不同的角色。项目经理在规划项目和对项目进行人员安排时，完成个人的角色安排。
</p>
<p class="node" align="left">
    尽管大多数角色由组织内的人员来实现，但开发组织外部人员也扮演重要角色：例如，正在开发中的项目或产品的<a class="elementLinkWithUserText" href="./../../../core.base_rup/roles/rup_stakeholder_1011D446.html" guid="{7A4262EA-AB5B-431E-BB4A-3822FBF7F239}">项目干系人</a>角色。
